摘要：

The selection of high strength solid buoyancy materials is an important key technology in the research and development of large depth unmanned / manned submersibles. This paper reviews the literature on solid buoyancy materials from three aspects: theory, experiment and fabrication technology. In terms of theoretical research, the theoretical research methods, research status, limitations and trends of elastic modulus prediction, mechanical property analysis and water absorption property prediction of solid buoyancy materials are introduced. In the aspect of experimental research, focusing on the hydrostatic pressure, dynamic compression and tensile experiments of buoyancy materials, macro deformation law and micro failure mechanism of materials are studied from macro and micro mechanics. In the aspect of the fabrication process, advantages and disadvantages of different preparation processes are introduced, and effects of different process methods on properties of buoyancy materials are introduced. Based on the literature research, some problems to be solved in the theoretical and experimental research and fabrication process of buoyancy materials are analyzed, and key research directions of solid buoyancy materials in the future are put forward. It is expected that the research in this paper can provide a comprehensive understanding of the mechanical behavior of solid buoyancy materials and provide certain theoretical support for the safety assessment of buoyancy materials of in-service full ocean depth unmanned / manned submersibles. © 2022, Editorial Office of Ship Building of China.
